Says who? Life is not a Mon-Fri 9-5 thing for everyone. If you need critical medications, and you ran out on Friday, should you roll the dice and see if you live through the weekend? The release of some prescription refills are very tightly controlled and cannot be sent early. If you are a business waiting for a signed contract, or a small mission-critical machine part or electronic circuit that can be sent via 1st class mail, do you shut down 'til Monday morning? Or should you incur 10X or more the postage so you can have it sent as a package? Steve, think outside your own living room!
